Lightly oil the sides and bottom of a 9" x 9" baking dish. Let veggies cool enough to handle. Slice the tomatoes, zucchini and squash approximately 1/4" thick. Alternate the veggies standing them in the pan. Pour the oil evenly over the veggies. Sprinkle with bread crumb mixture.

Cover the pan with foil and bake for 45 minutes. Uncover and continue to bake until "crispened up".
